BACKGROUND
[0003]
3,4-Methylenediomethamphetamine (MDMA), commonly known as ecstasy (E) or molly, is a psychoactive drug first developed in 1912 by Merck_MDMA is often used recreationally today. However, an initial use of MDMA was as an adjunct to psychotherapy.
More recently, MDMA has been studied in various clinical trials, for example, investigating MDMA-assisted psychotherapy for posttraumatic stress disorder (PTSD), anxiety related to advanced-stage illness, and social anxiety in autistic adults. MDMA has now been granted Breakthrough Therapy Designation for the treatment of PTSD by the United States Food and Drug Administration (FDA).

MDMA is generally available and consumed as a racemate. The racemate of MDMA is also known to have potential for adverse effects such as hyperthernnia and neurotoxicity. However, studies have shown qualitative differences in the effects of the isomers of MDMA. Evidence suggests that the R isomer of MDMA may provide an improved therapeutic index while maintaining some of the therapeutic effects of MDMA
racemate with a reduced side effect profile (Pitts et al. Psychopharmacology 235, 377-392, 2018, Curry et al.

[0005]
N-methyl-1,3-benzodioxolylbutanamine (MBDB) commonly known as Eden or Methyl-J, is an analogue of MDMA which has an ethyl group instead of a methyl group attached to the alpha carbon next to the amine. Like MDMA, MBDB is also classified as an entactogen. MBDB is also generally available and consumed as a racemate.
Therefore, there is also a need for further investigation of the prosocial, therapeutic and toxicological effects of each enantiomer or MBDB.

SUMMARY
[0006]
3,4-Methylenedioxymethamphetamine (MDMA) is generally administered as a racemate. The effect of the racemate of MDMA in social behaviour in humans has been studied. It is known that the racemate of MDMA exhibits adverse effects such as hyperthermia and neurotoxicity, and has the potential for drug abuse. The R enantiomer of MDMA ((R)-MDMA) has been shown to have prosocial effects with lower risk for adverse effects such as neurotoxicity and hypothermia. However, the S enantiomer of MDMA ((S)-MDMA) is known be the more potent enantiomer and to have the stimulant activity but it exhibits more adverse effects. Use of (R)-MDMA on its own, would result in loss of the stimulant activity and any synergistic effects provided from the S enantiomer.

[0007]
The Applicant therefore investigates various non-racemic mixtures of the enantiomers of MDMA which comprise a greater amount of the R enantiomer to develop a composition comprising a sufficient amount of the R enantiomer to achieve the desired prosocial effects while decreasing the occurrence of adverse effects, such as hyperthermia and neurotoxicity, of the S enantiomer, yet comprising a sufficient amount of the S enantiomer for therapeutic efficacy. The compositions of the application also have a lower potential for drug abuse. Similar such studies are carried out for the enantiomers of N-methyl-1,3-benzodioxolylbutanamine (MBDB). Through these detailed studies, the Applicant develops a composition comprising an optimum range for the ratio of the two enantiomers of these valuable therapeutic compounds, to provide the desired efficacy yet minimize the undesirable effects associated with the current use of the racemic mixtures.

At 2 mg/kg, maximum MDMA concentrations were ¨200 ng/ml for intraperitoneal (210 ng/ml) and subcutaneous routes (196 ng/ml), but less for the oral route (46 ng/ml). At higher doses, (10 mg/kg), Cmax via intraperitoneal (2257 ng/ml) and subcutaneous (1130 ng/ml) route of administration was higher than via oral route (966 ng/ml).

It is also known that the (R)- and (S)-enantiomers of racemic 3,4-methylenedioxymethamphetamine (MDMA) exhibit different dose-concentration curves.
MDMA, MDA, DHMA, DHMA sulfates, HMMA, HMMA sulphates, and HMMA glucuronides have been shown to be excreted in human urine in substantial amounts (Schwaninger AE, et al. Biochem Pharmacol. 2012;83(1):131-8). Statistically significant differences between the two enantiomers (R- and S- of individual metabolites) were observed for all compounds, except HMMA sulfate after creatinine normalization. Higher R-enantiomer Cmax was observed for MDMA, DHMA and HMMA sulfate, whereas S-enantiomers were higher for DHMA sulphate, HMMA, HMMA glucuronide, and MDA.Error! Reference source not found.

In some embodiments, intranasal administration is believed to offer both direct and indirect pathways to the delivery of psychopharmacological agents to the central nervous system (CNS). Direct nose-to-brain transport via olfactory and trigeminal nerve pathways after intranasal deposition and absorption on the olfactory and respiratory epithelia provides a non-invasive means of circumventing the blood-brain barrier (BBB), which is an obstacle for drug delivery to CNS. In some embodiments in comparison to other routes of administration (e.g.
oral administration), intranasal offers ease of use, reduced systemic exposure, faster drug onset, increased compliance, and greater bioavailability by avoiding first-pass metabolism (Keller et al. Drug Deliv. and Trans!. Res. 12,735-757 (2022))

A marked difference in the Cmax of MDMA in rats based on the route of delivery has been observed (Baumann MH et al., Drug Metab Dispos. 2009;37(11):2163-70).
At 2 mg/kg, maximum MDMA concentrations were ¨200ng/m1 for intraperitoneal (210 ng/ml) and subcutaneous routes (196 ng/nnl), but less for the oral route (46 ng/nnl). At higher doses, (10 mg/kg), Cmax via intraperitoneal (2257 ng/ml), and subcutaneous (1130 ng/ml) route of administration was higher than via oral route (966 ng/ml).

It is also known that the (R)- and (S)-enantiomers of racennic 3,4-methylenedioxymethamphetamine (MDMA) exhibit different dose-concentration curves.
MDMA, MDA, DHMA, DHMA sulfates, HMMA, HMMA sulphates, and HMMA glucuronides have been shown to be excreted in human urine in substantial amounts (Schwaninger AE, et al. Biochem Pharmacol. 2012;83(1):131-8). Statistically significant differences between the two enantiomers ((R)- and (S)- of individual metabolites) were observed for all compounds, except HMMA sulfate after creatinine normalization. Higher R-enantiomer Cmax was observed for MDMA, DHMA and HMMA sulfate, whereas S-enantiomers were higher for DHMA sulphate, HMMA, HMMA glucuronide, and MDA.Error! Reference source not found.

In some embodiments, intranasal administration is believed to offer both direct and indirect pathways to the delivery of psychopharmacological agents to the central nervous system (CNS). Direct nose-to-brain transport via olfactory and trigeminal nerve pathways after intranasal deposition and absorption on the olfactory and respiratory epithelia provides a non-invasive means of circumventing the blood-brain barrier (BBB), which is an obstacle for drug delivery to CNS. Further, in some embodiments, in comparison to other routes of administration (e.g oral administration) intranasal offers ease of use, reduced systemic exposure, faster drug onset, increased compliance, and greater bioavailability by avoiding first-pass metabolism (Keller et al. Drug Deliv. and Trans!. Res. 12, 735-757 (2022)).

[0302] Social Interaction Testing
[0303] A social interaction test that has been used to test the effects of MDMA, specifically to test prosocial effects of MDMA, is described in Morley and McGregnor Eur J
Pharmacol. 2000; 408:41-9, and is used to test the exemplary and comparative compositions of the application.
Pharmacol. 2000; 408:41-9, and is used to test the exemplary and comparative compositions of the application.
[0304] In order to familiarize subjects (mice) with the testing procedure and screen out aggressive subjects, the social interaction test is performed twice. During the first session, subjects receive injections of exemplary compositions of the application, comparative compositions or saline, and are isolated in clean cages for 30 minutes. Each subject is then paired with an unfamiliar weight-matched conspecific from the same treatment group in a 30 x 18 cm clear Plexiglas testing chamber for 10 minutes. An experimenter is present during the first test day to separate aggressive subjects. Any removed subjects are replaced with new naïve subjects so that each treatment condition has an equal number of non-aggressive subjects.
[0305] The second test session is performed 48 hours later using the same pairs, treatments, and procedure except that an experimenter is not present in the room during testing. While in the testing arena, subjects are free to move around and interact, allowing a diverse range of observable behaviors. On the second test day, the social pairings are videotaped and the duration of social behavior is quantified using JWatcher or BORIS (Friard and Gamba, Methods Ecol Evol. 2016; 7 (11) 1325-1330) by an observer blind to the experimental conditions. The durations of 3 behaviors are scored: anogenital investigation (sniffing the conspecific's anogenital area), general investigation (non-anogenital sniffing, grooming, and following the conspecific), and adjacent lying (side-by-side contact or huddling).
These behaviors are averaged for each pair and then summed to produce a total social interaction score, upon which statistical analysis is performed.
Locomotor Behaviour
These behaviors are averaged for each pair and then summed to produce a total social interaction score, upon which statistical analysis is performed.
Locomotor Behaviour
[0306] Effects of exemplary compositions of the application and comparative compositions on locomotor activity is tested in 45 x 39 x 37 cm open field chambers with 16 x 16 photocells positioned 2.5 cm off the chamber. Mice are treated with the exemplary compositions of the application, comparative compositions or saline (n =
13/group) immediately before being placed into the chambers for 1 hour. Testing is performed in a dark, enclosed space. Accumulative beam breaks of adjacent photocells are recorded as the measure of locomotor activity.

Fear Conditioning and Extinction
[0307] The effects of exemplary compositions of the application and comparative compositions on conditioned freezing are evaluated using an established protocol (Young et al., 2015,Transl Psychiatry. 5:1-8) previously used to test racemic MDMA. For consistency with this prior study, C57BL/6 mice are used in this experiment. Briefly, mice are exposed to cued fear conditioning on day 1, fear extinction training on day 3, and extinction testing on day 4. Cued fear conditioning consists of a single pairing of a conditioned stimulus (CS) tone (80 dB, 4.5 kHz, 30 s) and an unconditioned stimulus (US) foot shock (1 mA, 2 s).
Extinction training is carried out 48 hours later in a new context from conditioning. (R)-MDMA, (S)-MDMA, or saline (n = 6-7/group) were administered on day 3,30 minutes before training. Extinction training consists of a sub-optimal regimen of 4 C(S)-tone re-exposures separated by 45 seconds. Extinction testing is performed 24 hours later to determine the lasting effect of treatment on conditioned freezing. Extinction testing is performed in the same context as training and followed the same procedure except that no treatments is administered.
Throughout these experiments, percent freezing (the conditioned response) is estimated by scoring the presence or absence of non-respiratory movement every 5 seconds.

In a modified dosing regimen from Itzhak et al., Psychopharmacol. 2003;
166:241-248, subjects receive a total of four injections of exemplary compositions of the application, comparative compositions or saline given twice, two hours apart on two consecutive days. Subject are isolated during treatment and returned to their home cages 2 hours after the second daily dose. Following treatment, subjects are divided into two groups.
48 hours after the final injection, subjects from group 1 are anesthetized and transcardially perfused with 4% formaldehyde. Their brains are post-fixed overnight and then immersed in 15% sucrose for 48 hours, frozen in chilled methyl butane, sectioned at 35 pm, and stored at -20 C until analysis by immunohistochemistry. Subjects in group 2 are euthanized by cervical dislocation 14 days after the last injection. Their brains are removed and prefrontal cortex, striatum, and hippocampus are rapidly dissected and stored at -80 C for subsequent analysis by high-performance liquid chromatography (HPLC) or Western blot.

Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder defined by two main clusters of behaviors. The first group of behaviors is defined by deficits in social communication and social interaction, while the second group of behaviors consists of repetitive and inflexible patterns of behaviors, interests, and thoughts.
In 2016, the Autism and Developmental Disabilities Monitoring Network estimated ASD prevalence at 1 in 54 children, and stated that ASD was 4.3 times more prevalent among boys compared to girls.
Over the last several decades, the reported incidence of ASD has increased in the US, but the etiology of ASD remains poorly understood. To better understand the neurological basis of ASD, rodent models of ASD have been developed for research. The BTBR
T+Itpr3tf/J
mouse (BTBR), originally bred for studies on insulin-resistance, diabetes-induced nephropathy and phenyloketonuria, was identified approximately a decade ago as displaying strong and consistent autism-relevant behaviors. Identification of novel drugs which increase sociability and decrease repetitive behaviors in the autism-like BTBR mouse and in the C57BL/6J (057) background stock are therefore therapeutically useful in the context of ASD.
The bald patch often seen on the dorsal flank of BTBR mouse is due to repetitive grooming and "barbering" behavior exhibited by all mice of this strain, congruent with high rates of self-directed behavior which are characteristic of human ASD. Accordingly, the ability to remain blinded to strain is difficult.

Over the last several decades, the reported incidence of ASD has increased in the US, but the etiology of ASD remains poorly understood. To better understand the neurological basis of ASD, rodent models of ASD have been developed for research. The BTBR
T+Itpr3tf/J
mouse (BTBR), originally bred for studies on insulin-resistance, diabetes-induced nephropathy and phenyloketonuria, was identified approximately a decade ago as displaying strong and consistent autism-relevant behaviors. Identification of novel drugs which increase sociability and decrease repetitive behaviors in the autism-like BTBR mouse and in the C57BL/6J (057) background stock are therefore therapeutically useful in the context of ASD.
The bald patch often seen on the dorsal flank of BTBR mouse is due to repetitive grooming and "barbering" behavior exhibited by all mice of this strain, congruent with high rates of self-directed behavior which are characteristic of human ASD. Accordingly, the ability to remain blinded to strain is difficult.
[0314]
The studies described in Example 4 used male BTBR and 057 mice to evaluate the effects of racemic 3,4-methylenedioxymethamphetamine (MDMA) (e.g., comparative composition 1, MDMA)), its component S enantiomer (e.g comparative composition 3, (S)-MDMA)) and R enantiomer (e.g., exemplary composition 7, (R)-MDMA), and customized compositions comprising a non-racemic mixture of (R)-MDMA, or a salt and/or solvate thereof, and (S)-MDMA, or a salt and/or solvate thereof wherein (R)-MDMA or a salt and/or solvate thereof is present in the composition in a greater amount by enantiomeric equivalents, relative to (S)-MDMA, or a salt and/or solvate thereof (e.g., exemplary composition 2(i)) in an autism-relevant assay of social preference, as well as in studies of the safety and abuse liability of these drugs. Figure 1 provides the two dimensional molecular structures of methamphetamine (left structure) and 3,4-methylenedioxymethamphetamine (MDMA, right structure).
Pharmacologically, enantiomers can have very different biological effects, including quantitative differences in potency and effectiveness, as well as qualitative differences in mechanism of action or interoceptive effects. In the case of methamphetamine, the S(+)-enantiomer is an abused psychostimulant with potent and long lasting psychoactive effects, while the R(-)- enantiomer is more than 100-fold less potent at eliciting any of these effects. In the case of MDMA, both enantiomers are active, at similar doses, although they elicit effects which are different in kind from one another. Based on their similar chemical structures, methamphetamine was chosen as a positive control compound against which to compare the effects of MDMA in the social preference tests. Both compounds were expected to elicit locomotor stimulant effects at large doses, but methamphetamine was not expected to elicit any pro-social effects.

General animal handling
[0315] Adult male C57 and BTBR mice were shipped to the University of Arkansas for Medical Sciences from Charles River Laboratories and The Jackson Laboratory, respectively.
Upon arrival, mice were housed 3 per cage, according to strain, with food and water available ad lib. Mice were allowed to acclimatize to the UAMS facilities for at least 48 hours before any experimental procedures were performed.

Upon arrival, mice were housed 3 per cage, according to strain, with food and water available ad lib. Mice were allowed to acclimatize to the UAMS facilities for at least 48 hours before any experimental procedures were performed.
Drug administration:
[0316] All drugs were dissolved in physiological 0.9% saline and administered at a constant volume of 1 ml! 100 g body weight. Because all drugs utilized in these studies were synthesized as hydrochloride (HCI) salts, they were weighed as salts prior to the preparation of all solutions. All drugs at all concentrations are readily dissolved in an aqueous solution at normal pH. Injections of all drugs were administered intraperitoneally (IP) to mimic pharmacokinetic parameters typical of oral administration, without the Behaviour-impairing effects of gavage stress.
Social preference testing methods
Social preference testing methods
[0317] This assay was conducted in adult male 057 and BTBR
mice (n=6 per group) in a dedicated conditioning room where ambient light, sound, and human contact were tightly controlled . Social preference chambers consist of two polycarbonate boxes (13.5 cm wide x 22.5 cm tall x 31.0 cm deep), floored with rough-textured black ABS plastic, and connected to one another by a 1.25" PVC T-junction . An infrared photobeann emitter /
detector array is mounted at each intersection of the T-junction and each preference compartment, and as a mouse traversed the apparatus, it would break the photobeam upon entry to or exit from each preference compartment. Beam breaks started or stopped a counter on an interfaced computer, allowing automated collection of time spent in each compartment. At the end of each test, data were reported as time (in seconds) spent in each compartment, the number of entries into each compartment, and the average time spent in each compartment following an entry. Social preference tests were conducted in an iterative manner, with each test subject completing four distinct phases as described below. Between testing sessions, chambers were sanitized by wiping the insides with a disinfectant product provided by the UAMS
Department of Laboratory Animal Medicine. At the end of the week (upon completion of all phases of the procedure), each apparatus was disassembled and all parts were sanitized. No food or water were available during social preference sessions, but were available in the home cage immediately afterwards.

No food or water were available during social preference sessions, but were available in the home cage immediately afterwards.
Phase 1 ¨ Habituation
[0318] A single habituation session occurred prior to preference testing, where each compartment contained an identical empty wire mesh pencil cup (9.0 cm diameter x 10.5 cm tall). During this session, mice were weighed, no injection was administered, and subjects were introduced into the T-junction and allowed to explore both preference compartments for 30 minutes. This habituation session was conducted as a procedural control to allow animals to become accustomed to the apparatus and to screen out any animals with a strong initial bias for one of the two compartments. An a priori exclusion criterion was established such that any subjects spending more than 75% of the total time in one single preference compartment would be excluded from further study, but no subjects in these studies met this standard for exclusion. Habituation sessions always occurred on Mondays or Tuesdays to prevent any weekend testing.
Phase 2 ¨ Novelty preference
Phase 2 ¨ Novelty preference
[0319] A single novelty preference session occurred the day after the habituation test, where one compartment contained an empty wire mesh cup and the other compartment contained an identical wire mesh cup with a novel dummy mouse inside. The position of the dummy mouse (left or right compartment) was counterbalanced across subjects.
Dummy mice were constructed from 2.5" lengths of white 3/4" PVC pipe, with a zip tie attached to one end (to mimic a tail) and two red dots drawn on the other end (to mimic eyes.) During this session, mice were weighed, administered an injection, and returned to their home cage for a 30 min pretreatment period. Mice were then introduced into the T-junction and allowed to explore both preference compartments for 15 minutes. These tests were conducted as a procedural control to ensure that any observed drug effects were not simply due to enhancement of the innate novelty preference of mice. Novelty preference sessions always occurred on Tuesdays or Wednesdays to prevent any weekend testing.
Phase 3 ¨ Sociability testing
Dummy mice were constructed from 2.5" lengths of white 3/4" PVC pipe, with a zip tie attached to one end (to mimic a tail) and two red dots drawn on the other end (to mimic eyes.) During this session, mice were weighed, administered an injection, and returned to their home cage for a 30 min pretreatment period. Mice were then introduced into the T-junction and allowed to explore both preference compartments for 15 minutes. These tests were conducted as a procedural control to ensure that any observed drug effects were not simply due to enhancement of the innate novelty preference of mice. Novelty preference sessions always occurred on Tuesdays or Wednesdays to prevent any weekend testing.
Phase 3 ¨ Sociability testing
[0320] A single sociability session occurred the day after the novelty preference test, where one compartment contained a wire mesh cup with a dummy mouse inside while the other compartment contained a male NIH Swiss stranger mouse inside the previously empty cup . The wire mesh cups allowed visual, olfactory, auditory, and limited tactile contact, but prevented aggressive behaviors which may otherwise have resulted in injury.
The position of the dummy mouse (left or right compartment) remained the same for each subject as during the novelty test the day before, thereby counterbalancing the position of the stranger mouse across subjects. NIH Swiss stranger mice were similar in mass and appearance to the dummy PVC mice, and were housed separately from the experimental subjects (057 and BTBR mice) in the colony facility. The first time the experimental subjects ever encountered the stranger mice was when they entered the compartment where they were contained. During this session, mice were weighed, administered the same injection as the day before, and returned to their home cage for a 30 min pretreatment period. Mice were then introduced into the T-junction and allowed to explore both preference compartments for 15 minutes.
Sociability tests always occurred on Wednesdays or Thursdays to prevent any weekend testing.
Phase 4 ¨ Social novelty preference
The position of the dummy mouse (left or right compartment) remained the same for each subject as during the novelty test the day before, thereby counterbalancing the position of the stranger mouse across subjects. NIH Swiss stranger mice were similar in mass and appearance to the dummy PVC mice, and were housed separately from the experimental subjects (057 and BTBR mice) in the colony facility.

Sociability tests always occurred on Wednesdays or Thursdays to prevent any weekend testing.
Phase 4 ¨ Social novelty preference
[0321] A single social novelty preference session occurred the day after the sociability test, where one compartment contained a wire mesh cup with the same NIH Swiss mouse from the previous day inside (referred to now as the "familiar" mouse) while the other compartment contained a new male NIH Swiss stranger mouse inside the cup which previously contained the dummy mouse during the sociability test . The wire mesh cups allowed visual, olfactory, auditory, and limited tactile contact, but prevented aggressive behaviors which may otherwise have resulted in injury. The position of the now familiar NIH
Swiss mouse (left or right compartment) remained the same for each subject as during the sociability test the day before, thereby counterbalancing the position of the new NIH Swiss stranger mouse across subjects. As before, the new NIH Swiss stranger mice were housed separately from the experimental subjects (C57 and BTBR mice) in the colony facility, and the first time the experimental subjects ever encountered them was when they entered the compartment where they were contained. During this session, mice were weighed, administered the same injection as the day before, and returned to their home cage for a 30 min pretreatment period. Mice were then introduced into the T-junction and allowed to explore both preference compartments for 15 minutes. Social novelty tests always occurred on Thursdays or Fridays to prevent any weekend testing.

Social preference testing results Drug effect on locomotor activity
[0322]
Quantification of total entries into the preference compartments provided a proxy measurement for locomotor stimulant effects of the various doses of the various test drugs. This established a limit to the drug doses that can be tested in the social preference procedure, as induction of locomotor stimulant effects confounds preference assessments (because mice stop attending to the social stimuli in each compartment and instead spend their time engaged in locomotor behavior.) Motor activity varied across the distinct phases of social preference testing, in part because the habituation session is twice as long (30 minutes) as the novelty, sociability, and social novelty tests (15 minutes each), but also because mice emitted high levels of exploratory behavior in novel environments. Thus, as familiarity with the test apparatus increased over successive exposures to the chambers, the number of entries decreased.

[0323]
Figure 2 illustrates this decreasing trend in motor activity in 057 (filled black bars) and BTBR (open white bars) in the absence of any drug injections.
Baseline differences in locomotor activity were also observed between the C57 and BTBR mice in the absence of drug injection, such that BTBR subjects always exhibited more entries during every phase of the social preference procedure.

[0324]
Because baseline activity for 057 and BTBR mice did not change from the sociability to the social novelty test (the final testing phase, when mice are at maximum familiarity with the apparatus), the focus was on drug effects during this phase to determine locomotor stimulant effects of the various treatment drugs. (Note that entries were collected for every test, but drug effects on entries during earlier phases may be less reliable due to the confounding influence of changing familiarity with the apparatus across phases.)

In C57 mice (see Figure 3, black bars), approximately 20 entries were observed following the administration of saline.

Injection of methamphetamine (positive control), racemic MDMA (e.g, comparative composition 1) and S(+)-MDMA (e.g., comparative composition 3) dose-dependently increased entries to over 150, indicating locomotor stimulant effects which confound the assessment of social preference following 3.0 mg/kg methamphetamine, 10.0 mg/kg racemic MDMA (e.g. comparative composition 1) and 10.0 mg/kg S(+)-MDMA
(e.g.
comparative composition 3) (see Figure 4). In contrast, administration of 10.0 mg/kg R(-)-MDMA (e.g. exemplary composition 7) did not increase compartment entries.

[0327]
However, in BTBR mice (see Figure 4, right pane open bars), approximately 40 entries were observed following administration of saline, consistent with their greater baseline levels of locomotor activity previously described in Figure 2.

[0328]
Injection of racemic MDMA (e.g., comparative composition 1) dose-dependently increased entries to close to 100 at 5.6 mg/kg, suggesting a more potent locomotor stimulant effect in BTBR mice than in C57s. A single dose of S(+)-MDMA (e.g comparative composition 3)was tested, and similar to the C57 mice, 3.0 mg/kg S(+)-MDMA
(e.g. comparative composition 3) elicited roughly equivalent entries to 3.0 mg/kg racemic MDMA (e.g comparative composition 1). Because no dose of racemic MDMA (e.g comparative composition 1) or S(+)-MDMA (e.g comparative composition 3) increased entries to more than 100, all tested doses are presented in the social preference results described below.

C57 mice (see Figure 5, left graph) exhibited no strong preference for the dummy mouse over the empty cup, as approximately equal amounts of time was spent in each compartment following administration of saline. Injection of methamphetamine, S(+)-MDMA
(e.g comparative composition 3) or R(-)-MDMA (e.g. exemplary composition 7) had no systematic effects on novelty preference, but administration of racemic MDMA
(e.g comparative composition 1) elicited avoidance of the dummy mouse at the 5.6 mg/kg dose.

[0331]
No dose of racemic MDMA (e.g comparative composition 1) or S(+)-MDMA
(e.g comparative composition 3) elicited any effects on novelty preference.
Because none of the test drugs increased novelty preference, any enhancement of social preference in subsequent tests is unlikely to be confounded by novelty-related effects, such as changes in the motivational properties of novel objects, which might otherwise be confused for pro-social effects.

Injection of methamphetamine or S(+)-M DMA (e.g comparative composition 3) had no systematic effects on sociability, but administration of racemic MDMA
elicited a dose-dependent increase in time spent with the stranger mouse, producing a moderate preference for the stranger over the dummy at the 3.0 mg/kg dose. The largest effect on sociability was elicited by administration of 10.0 mg/kg R(-)-MDMA (e.g exemplary composition 7).
Interestingly, these doses of racemic MDMA (e.g comparative composition 3) and R(-)-MDMA

In BTBR mice (see Figure 3, right bar), the expected autism-like social decrement was observed following saline administration, where mice exhibited a strong avoidance of the stranger mouse. Administration of racemic MDMA elicited a similar biphasic effect on sociability as observed in the C57s, with the smallest tested dose having no effect, intermediate doses increasing preference for the stranger mouse, but these pro-social effects were not observed after injection of the largest dose. Also similar to C57 mice, the single dose of S(+)-MDMA (e.g comparative composition 3) tested did not alter sociability in the BTBRs (See Figure 6). In contrast to the dissociation of locomotor effects from pro-social effects observed in the 057 mice, BTBR mice only exhibited increased sociability following administration of racemic MDMA (e.g comparative composition 1) doses which increased motor activity (as previously seen).

Racemic MDMA (e.g comparative composition 1), S-(+)-MDMA (e.g comparative composition 3) stimulated the motor activity in C57 mice in a dose-dependent manner, with over 100 entries documented at 10mg/kg, intraperitoneal administration (see8, top left graph). In contrast, even at 10mg/kg R-(-) MDMA (e.g exemplary composition 7) has no stimulant effect on the motor activity of C57. Exemplary composition 2(i) comprising 80%
(R)-MDMA and 20% (S)-MDMA dosed at higher doses has some stimulant effect, but it is substantially lower than that observed for S-MDMA (e.g comparative composition 3) and racemic MDMA(e.g comparative composition 1).

(R)-MDMA and 20% (S)-MDMA dosed at higher doses has some stimulant effect, but it is substantially lower than that observed for S-MDMA (e.g comparative composition 3) and racemic MDMA(e.g comparative composition 1).
[0340]
057 mice, upon administration of 10mg/kg R-MDMA (e.g exemplary composition 7) exhibited a strong preference for the new stranger mouse, as more time, was spent in the compartment containing the new stranger mouse than in the compartment containing the now familiar mouse (bottom right graph, Figure 8). In contrast, even after administration of 3.0mg/kg and 5.6mg/kg of S-MDMA (e.g comparative composition 3), C57 does not elicit any substantial preference for the stranger mouse compared to the now familiar mouse (bottom right graph, Figure 8). Racemic MDMA (e.g comparative composition 1) demonstrated a bi-phasic dose-response preference for stranger mouse over familiar mouse, with maximum preference documented at 3mg/kg dose. Exemplary composition 2(i) dosed at 10mg/kg elicited a strong preference for the stranger mouse without overly stimulating the mouse, as is seen with Racemic MDMA (e.g comparative composition 1).

When studying the impact of the drugs on the novelty preference (preference for a novel dummy mouse over an empty cup), no systemic effects were observed in either strain, based on data (see -Figure 9). This was a control experiment to ensure that observed drug effects in subsequent social preference tests are truly related to the social behaviour as opposed to changes in salience of novel stimuli.

For 057 mice, racemic (50/50) MDMA (e.g comparative composition 3), exemplary composition 2(i) comprising 80% (R)-MDMA and 20% (S)-MDMA d, and pure R-MDMA (e.g, exemplary composition 7) elicit significant effects on sociability at the 3.0 mg/kg dose, but the effects of pure S-MDMA (e.g comparative composition 3), are not different from saline (see Figure 10). For the BTBR mice, there appears to be a "dose-dependent" effect such that the more R-MDMA is present in the mixture, the bigger the effect (although there may be a plateau as exemplary composition 2(i)-is identical to the pure R-MDMA
(e.g, exemplary composition 7.) Thus exemplary composition 2(i)-elicits a stronger sociability response than Racemic MDMA (e.g comparative composition 1) and S-MDMA (e.g comparative composition 3).

(e.g comparative composition 3), are not different from saline (See Figure 11). For the BTBR
mice, there again appears to be a "dose-dependent" effect such that the more R-MDMA is present in the mixture, the bigger the effect with exemplary composition 2(i) performing nearly similar as R-MDMA
(e.g exemplary composition 7). It is important to take this into consideration along with the locomotor stimulant effect captured in Figure 12. For 057 mice, none of the MDMA
formulations significantly altered entries. For the BTBR mice, pure S-MDMA
(e.g comparative composition 3), and the racemic mixture (e.g comparative composition 1) increased the number of entries observed at this dose, but no stimulation of motor activity was observed with exemplary composition 2(i) comprising 80% (R)-MDMA and 20% (S)-MDMA), while pure R-MDMA (e.g exemplary composition 7) reduced entries at this dose.
Summary:

Summary:
[0344]
In summary, it has been demonstrated that S-MDMA (e.g comparative composition 3) and Racemic MDMA (e.g comparative composition 3) have a dose-response stimulant effect on the 057 mice (representative of the general population) and BTBR mice (representative of the autistic population), while R-MDMA (e.g exemplary composition 7) at higher doses (3 mg/kg) suppresses the locomotor activity in BTBR mice.
Exemplary composition 2(i) comprising 80% (R)-MDMA and 20% (S)-MDMA does not influence the locomotor activity in BTBR and C57 mice.

[0345]
The influence of exemplary composition 2(i) on pro-social behaviour is well captured through the social novelty preference test, where at 3 mg/kg administration (i.p) in BTBR and 057 mice, the mice under the influence of the drug have a strong preference to interact with and spend time with a stranger over mouse over a familiar mouse.
The time spent with the stranger is much more than that observed under the influence of Racemic MDMA (e.g comparative composition 1) and S-MDMA (e.g comparative composition 3).

Monoamine-mimetic agents can affect temperature control, particularly amphetamine derivatives such as MDMA, which has perhaps been most widely studied (Freedman et al., Psychopharmacology, (2005) 183, 248-256; Kendrick et al., (1977) Annals of Internal Medicine, 86, 381-387; Parrott, AC (2012) Drug and Alcohol Dependence, 121, 1-9; Docherty & Green, (2010), British Journal of Pharmacology, 160, 1029-1044).
Thus, the purpose of this study was to study the impact of the drug(s) of interest on the core body temperature of C57 and BTBR mice. Building on the social preference demonstrated by exemplary composition 2(i)the impact of the such non-racemic compositions of the application and (R)-MDMA (exemplary composition 7) was included in this study.

Prior to surgical implantation of radiotelemetry probes, mice received 3 mg/kg meloxicam (IP), and anesthesia was induced with 4% inhaled isoflurane and maintained with 1-3% isoflurane (as needed) throughout the procedure at a flow rate of 1.5 litres/minute. The abdominal area of each animal was treated with depilatory cream, then sanitized with 3 alternating scrubs with iodine and alcohol. A rostral-caudal cut approximately 1.5 cm in length was made with sterile skin scissors, providing access to the intraperitoneal cavity. A cylindrical glass-encapsulated radiotelemetry probe (model ER-4000 E-Mitter, Mini Mitter, Bend, OR, USA) was then inserted. These probes measure 15.5 mm x 6.5 mm and weigh approximately 1 gram. Incisions were closed (skin layer and muscle layer separately) using reverse cutting 5-0 Vicryl absorbable sutures for the muscle layer and 5-0 nylon suture material for the skin layer. Surgeries were carried out at least 7 days before initiation of experimental conditions, allowing time for incisions to heal and for animals to recover normal body weights. Following surgery, all implanted mice were individually housed in Plexiglas cages within the telemetry room for the duration of all experiments. Implanted transmitters produce activity- and temperature-modulated signals which are sent to a receiver (model ER-4000 Receiver, Mini Mitter Co., Inc.) underneath each cage. Following use, telemetry probes were removed from carcasses, wiped with alcohol swabs, and stored in the disinfectant solution until re-use.

[0349]
At least 7 days after surgical implantation of radiotelemetry probes, mice in their individual home cages were placed atop a telemetry energizer/receiver, which powered probes and transmitted their data to an interfaced computer. Upon initiation of an experimental session, the computer collected two data updates from the probes at 5 min intervals: core temperature (in C) on one channel, and locomotor counts (in arbitrary units, depending on the relative position of the probe atop the receiver) on the other. After at least 60 minutes of baseline data collection, mice were removed from their cages, injected with saline or a given dose of a specific drug, then returned to the home cage 24 hours of data collection.

[0350]
Food and water were always freely available in the home cage. Mice were injected with ascending doses of a given drug, with at least 48 hours separating doses.
Because there are few studies of drug effects in BTBR mice, the first drug dose tested occasionally elicited unexpectedly large locomotor effects in these animals.
In these cases, smaller drug doses were tested next, after a washout period of at least one full day.

[0351]
Figure 13 shows the saline injection on core temperature (left panel) and locomotor activity (right panel) in 057 (filled circles) and BTBR mice (filled circles. Both strains display a transiently increased core temperature and higher activity levels for approximately 30 min following saline administration. The activity also follows the normal circadian pattern for both strains. More motor activity was recorded during the subjective dark phase, but interestingly, the BTBR mice exhibit more activity than the C57s, along with an elevated core temperature likely due to this higher activity.

Effect of increased doses of Racemic MDMA injection on the core temperature in C57 and BTBR mice
[0352] Figure 14 shows the effect of various doses (10 mg/kg, 30 mg/kg, 56 mg/kg, 100 mg/kg) of racemic MDMA (e.g. comparative composition 1) on the core temperature in 057(filled circle) and BTBR mice (open circle). Because lethality was expected at the 100 ring/kg dose, injections, at this dose, were administered at the start of the workday and room lights, therefore, remained on for the duration of the data traces shown here.
[0353] At 10mg/kg IP administration, Racemic MDMA (e.g.
comparative composition 1) induced a drop in core temperature in both 057 and BTBR mice 30m1ns -1h after injection which subsequently stabilized. Increasing the doses saw a gradual increase in core temperature in both BTBR and C57 mice; with a nearly 2 degrees C rise in temperature at 56mg/kg.

[0354] Figure 15 shows the effects of various doses of racemic MDMA (e.g.
comparative composition 1) on locomotor activity in C57 (filled circles) and BTBR (open circles) mice. The pattern of locomotor activity (see 15) across the time course for the C57s administered 30, 56 and 100 mg/kg is consistent with motor stereotypy: an initial increase in activity is observed, followed by suppression of locomotion, then a "late phase" increase in activity as MDMA is cleared and eliminated. No evidence of motor stereotypy in the BTBR was observed at any dose. The increased locomotor effect corresponds to the modulation in temperature as documented in 14 above.

[0355] Figure 16 shows the effect of various doses of S-MDMA
(e.g. comparative composition 3) on core temperature in 057 (filled circles) and BTBR (open circles) mice. Note that the large error bars in the 057 data trace from approximately 5-8 hrs after injection were due to one animal experiencing profound hypothermia before expiring. The abrupt "jump" in mean temperature is a consequence of this subject being removed from group average after death.

[0356] Like Racemic MDMA (e.g. comparative composition 1), S-MDMA (e.g.
comparative composition 3) elicits a dose-dependent increase in temperature in both 057 and BTBR mice with the key distinction being that lower doses of S-MDMA elicit a stronger change in core temperature. The jump in core temperature at 18mg/kg i.p administration of S-MDMA
(e.g. comparative composition 3) (16) is greater than that observed by administration of 56mg/kg i.p of Racemic MDMA (e.g. comparative composition 1) (14) Effect of increased doses of S- MDMA injection on LMA in 057 and BTBR mice

The pattern of locomotor activity across the time course for the C57 mice administered 30 ring/kg is consistent with motor stereotypy: an initial increase in activity is observed, followed by suppression of locomotion, then a "late phase" increase in activity as S(+)-MDMA is cleared and eliminated. No evidence of motor stereotypy in the BTBR was observed at any dose.

Figure 18 shows the locomotor effects 01 0.3 mg/kg (top left), 1 mg/kg (top right graph), 3 mg/kg of u-opioid agonist Fentanyl in C57 mice (filled circles) vs BTBR mice (open circles). Note that unlike the pattern of data observed with racennic MDMA
(e.g. comparative composition 1) and S(+)-MDMA (e.g. comparative composition 1), each dose of fentanyl elicited more locomotor activity in the C57 mice than in the BTBR mice. Thus, BTBR mice are not more sensitive to locomotor effects of all drugs but are specifically sensitive to psychostimulant effects of MDMA-like drugs.

For C57 mice (left), pure S(+)-MDMA (e.g., comparative composition 3) elicited an increase in temperature, but neither of the mixtures (e.g., exemplary composition 2(i)) nor pure R(-)-MDMA (e.g., exemplary composition 7) elicited significant effects on the core temperature at this dose. There looks to be a trend toward decreasing temperature as a function of the presence of R(-)-MDMA, whether these are physiologically relevant for the human populations remains to be evaluated.

[0361] For BTBR mice (right), pure S(+)-MDMA (e.g., comparative composition 3) elicited a similar increase in temperature, and the less S(+)- enantiomer present in the mixtures, the smaller the observed effect. This pattern is repeated at the 30 mg/kg dose below where significant differences are observed.

For C57 mice (left), pure S(+)-MDMA
(e.g., comparative composition 3), elicits the greatest locomotor stimulation, and lesser hyperactivity is observed with the racemic mixture (e.g., comparative composition 1), and the 80R/20S

mice (right), pure S(+)-MDMA (e.g., comparative composition 3) elicited a substantially large stimulation in motor activity, and the less S(+)- enantiomer present in the mixtures, the less activity was observed.

For C57 mice (left), pure S(+)-MDMA
(e.g., comparative composition 3), elicits the greatest locomotor stimulation, and lesser hyperactivity is observed with the racemic mixture (e.g., comparative composition 1), and the 80R/20S
mixture (e.g., exemplary composition 2(i)) at this dose. Pure R(-)-MDMA (e.g., exemplary composition 7) did elicit significant motor stimulation at this dose. For BTBR

[0363] Surprisingly, despite the strong locomotor stimulant effect with S-MDMA (e.g., comparative composition 3) in BTBR mice (Figure 21), the core temperature did not differ much from that observed with Racemic MDMA (e.g., comparative composition 1) (see Figure 20).

[0365] For BTBR mice (right), pure S(+)-MDMA (e.g., exemplary composition 3), elicited a large hyperthermic response, and the less S(+)- enantiomer present in the mixtures, the less hyperthermia was observed. For pure R(-)-MDMA (e.g., exemplary composition 7) and for the 80/20 mixture (e.g., exemplary composition 2(i), no significant effects on core temperature were observed at this dose.

[0367] For C57 mice (left graph), the racemic mixture (e.g., comparative composition 1) and the 80R/20S mixture (e.g., exemplary composition 2(i)) elicit more activity than the pure S(+)-MDMA(e.g., comparative composition 3), due to stereotypic effects of the S(+)-enantiomer at this dose. Pure R(-)-MDMA (e.g., exemplary composition 7) did not elicit significant motor stimulation at this dose.
[0368] For BTBR mice (right), pure S(+)-MDMA elicited a large stimulation in motor activity, and the less S(+)- enantiomer present in the mixtures, the less activity was observed.

Both racemic MDMA (e.g., comparative composition 1) and S(+)-MDMA (e.g., comparative composition 3) elicit a classical "inverted U-shaped" dose-effect curve as large doses elicit motor stereotypy which results in less total ambulatory activity than observed at intermediate doses.
Interestingly, the dose-effect curve for the BTBR mice does not follow this biphasic pattern for racemic MDMA.
Summary
Interestingly, the dose-effect curve for the BTBR mice does not follow this biphasic pattern for racemic MDMA.
Summary
[0370] In a Pilot Phase 2 clinical trial, Alicia Danforth, and Charles Grobb (Danforth et al., Psychopharmacology (Berl). 2018; 235(11): 3137-3148), have demonstrated rapid and durable improvement in social anxiety symptoms in autistic adults following MDMA-assisted psychotherapy. However, Racemic MDMA also results in a rise in core temperature and cardiovascular events as demonstrated by other researchers. The aim of the present study was to evaluate the safety profile of our exemplary non-racemic compositions of the application compared to the individual (R) and (S) enantiomers of MDMA and Racemic MDMA.
[0371] The following findings were found:
[0372] Both racemic MDMA (e.g., comparative composition 1) and S(+)-MDMA (e.g., comparative composition 3) elicit a classical "inverted U-shaped" dose-effect curve as large doses elicit motor stereotypy which results in less total ambulatory activity than observed at intermediate doses. Interestingly, the dose-effect curve for the BTBR mice does not follow this biphasic pattern for racemic MDMA (see Figure 24)
[0373] In comparison to 10mg/kg, BTBR elicits a strong hyperthermic response to 30mg/kg S-MDMA (e.g., comparative composition 3). Racemic MDMA (e.g., comparative composition 1) at both doses (10mg/kg and 30mg/kg) results in an increase in temperature but is not as significant as S-MDMA. (see Figure 22).
[0374] Exemplary composition 2(i)) (regardless of the dose) and Saline have a response to change in temperature in BTBR and C57 mice (see Figure 20 and Figure 22).
[0375] These results in combination with the Social Preference data described in Part A above elucidate that upon administration of non-racemic composition of the application such as exemplary composition 2(i)) in BTBR mice, the mice overcome the inherent social anxiety without having severe adverse events such as hyperthermia. Thereby non-racemic compositions of the application such as exemplary composition result in a relatively safer use of MDMA.
